The Japanese camera maker announced Wednesday it's developing the M.Zuiko Digital ED 7-14mm F2.8 Pro ultra-wide zoom and the M.Zuiko Digital ED 300mm F4 Pro supertelephoto. In 35mm camera terms, those have the focal-length equivalents of 14mm-28mm and 600mm, respectively.

The lenses will be the third and fourth models of Olympus' new Pro line. The first arrived in 2013, the M.Zuiko Digital ED 12-40mm f/2.8 Pro, which my colleague Lori Grunin really liked and which has an equivalent range of 24-80mm.

Next up is the M.Zuiko Digital ED 40-150mm F2.8 Pro, due in the second half of 2014 and bringing and equivalent range of 80-300mm.
